COFFEE-ROASTER.

SPECIFICATION forming part of Letters Patent No. 374,933, dated December 20, 1887.

Application filed June 27, 1887.

To aZZ whom, it may concern: Be it known that we, JOHN W. BURT an GEORGE W. TRUSTY, of Cascilla, in the county of Tallahatchie and State of Mississippi, have invented certain new and useful Improvements in Coffee-Roasters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification.

Our invention relates to an improvement in coffee-masters which is especially intended to be used in connection with the oven-doors of cooking stoves; and it consists in the combination of the perforated oven-door, the pipe which passes through the opening in the door and is clamped or held in ahorizontal position, the supporting-frame clamped against the door and provided with arms which extend inwardly into the oven, the frame in which the cylinder is journaled, and a supporting-frame which is attached to the end of the cylinder-frame and which is made to catch upon the support which is clamped to the door, and the operating-shaft which passes through the pipe and by means of which the cylinder is revolved, as will be more fully described hereinafter, and set forth in the claim.

Figure l is a side elevation of a roaster embodying our invention attached to an ovendoor. Fig. 2 is a plan view. Fig. 3 is a detail perspective of the supporting-hooks.

A represents the oven-door of an ordinary cooking-stove, having a hole through which the screw-threaded pipe B passes and securely held by means of the nuts and washers O O. Passing through the pipe B is the operatingshaft D, which has a pin, E, passed through it to limit its inward movement. Theinner end of the shaft D is made screw-threaded and has the nut F placed thereon for the purpose of limiting the. outward movement of the operating-shaft through the screw-threaded pipe B. A bifurcated plate, G, is screwed or riveted to the end of the operatingshaft D, for a purpose hereinafter described.

Olamped between the inner side of the ovendoor and the inner nut C, which also serves to hold the pipe B rigidly in its proper position, is the downwardly extending rod H,

Serial No. 242,647. (No model.)

which is bifurcated where the hollow pipe B passes through it, and has its bifurcated ends extending horizontally in opposite directions along the inner side of the oven-door a suitable distance, as shown in Fig. 2, and then outward from the door, as shown, forming the arms H, and their outer ends provided with the upturned ends or hooks I. Resting in the notch J, made in the lower end of the rod H, is the lower end of the flat bar K, which has a recess for receiving the face of the rod H. The upper end of the bar Kis bifurcated and has its bifurcated ends L fastened to the end of the oblong or rectangular frame M, in which the cylinder N is journaled. The upper and lower ends of the flat bar K are inclined toward the oven-door and away from the frame M, as shown in Fig. 1. The upper ends, L, catching over the ends I and the lower end of the bar K catching in a notch formed in the lower end of the rod H, the cylinder is firmly supported in a horizontal position.

Passing through the cylinder N is the shaft P, the ends of which are journaled in the ends of the frame M. The inner end of the shaft 1? is provided with a pin, Q, with which engages the bifurcated plate G upon the end of the operating-shaft, and by means of which a rotary motion is imparted to the cylinder. Coffee is placed in the cylinder through the door It, madein the inner end of the cylinder, the door being held closed by means of a ring upon the door and a projection upon the cylinder, as shown. The frame M does not interfere in any manner with the opening of the door when the cylinder is in the position shown in Fig. 1, as it does not extend down to a point within the horizontal line of the end of the frame. The cylinder is preferably perforated, as shown, which materially aids the roasting of the coffee.

\Ve here show a handle, S, for operating the shaft D; but, if desired, the shaft may be rotated by means of a belt running from any suitable spring or weight motor to the pulley T upon the outer end ofthe shaft D. Theinner end of the shaft D being screw-threaded and having the nut F thereon, the endwise movement of the shaft through the hollow pipe B may be regulated as-desired. hen the nut is moved inwardly upon the screw-shaft D until it bears against the bifurcated plate G, the

shaft can be moved freely back and forth through the pipe B, and it can be pushed inward until the bifurcated plate engages the pin Q upon the cylinder-shaft P, the cylinder given a rapid revolution, and the shaft D withdrawn until the plate G and pin Q are disengaged, thus allowing the cylinder to revolve from the momentum given it.

By means of the devices herein described for supporting the frame M and cylinder N horizontally within the oven the cylinder may be instantly removed from the door for any purpose desired, and thus not monopolize the room of the oven when not in use.

In order to attach our roaster to the ovendoor of any stove now in use, it is only necessary to bore a hole through the door-for the passage of the screw-threaded pipe B, when the Whole device can be almost instantly ad- It is designed i that the shaft D and hooks I shall remain upon the door, as they are so far from the bottom of I the oven as not to interfere with anything which may be placed therein.

Having thus described our invention, we claim- The combination of the perforated ovendoor, the pipe B, which passes through the opening and is clamped or held in a horizontal position, the supporting-frame H H I, clamped against the door, the frame M, the cylinder N, journaled therein, the supportingframe K L, attached to the end of the frame M and made to catch upon the support which is clamped to the inner side of the door, and the operating-shaft which passes through the pipe B, substantially as shown.

In testimony whereof we affix our signatures in presence of two Witnesses.
